FAQ

Can I use the effect with components other than SpriteRenderer (UI Image, Tilemap, etc)?

Not directly (after all, this is SpriteGlow), but it's possible if the component is using a shader similar to sprites (e.g UI objects, tilemaps and other "2D" stuff). For this you will have to create a material based on the Sprites/Outline shader and manually apply it to the component. You can then control all the glow parameters using the material editor. In the project you can find scenes with the examples for applying the effect to UI Button and a tilemap.

Why the glow appears on the whole image?

Make sure 'Threshold' value of the bloom image effect is set high enough. It's usually 1 to 1.5, depending on the bloom solution.

Why I get a NullReferenceException in build?

Most likely the outline shader is not included to the build (it happens when none of the included assets reference SpriteGlow component directly). You can force-include the shader by assigning it to the "Always Included Shaders" in Edit -> Project Settings -> Graphics.
